SAFE.

Application med inne 1o, 1922. serial No. 67,501.

To all whom 'it may concern.'

@Be it known that I, REINHoLn BRUER, a

citizen of the German Republic, residing aty To overcome the difficulties of transport,

safes are sometimes constructed out of detachable blocks which are'assembled in situ and connected by internal lelements which are inaccessible when the safe is closed.

The invention relates to a safe of this kind and consists in forming the body of the safe out of a plurality of nested frames which are clamped, together between a front frame and a rear wall.

A safe constructed in this manner will, while being easy to transport and to erect, ensure the same degree of safety as those constituting an integral structure.'

In the accompanying drawings Fig. 1 represents a vertical section of a safe having a single compartment, Fig-.2, a horizontal section of the same, Fig. 3,- a vertical section showing a combination of two superposed. safe-compartments,

Fig. 4, a vertical section at right angles to Fi 3,

Fig. 5, a horizontal section of Fig. 3, and Fig. 6, a front view of the entire structure. Fig. 7 is a vertical section showing a combination of two safe compartments ar ranged in juxtaposition, and

Fig. 8, a .front view of the same.

Figs. 9 and 10 are corresponding views showing a combination of four safe-compartments. j Fig. 11 is a horizontal section of this arrangement, and

Fig. 12, a top view of the same. Fig. 13 is a front view showing how any number of safes can4 be combined in juxtaposition. l

The back wall of the safe is composed of a slab a which may be made of concrete and suitably reinforced. Anchored to. the reinforcements are screw-bolts z' which project into the interior of the safe and serve as means for securing the various parts together. The rest of the safe is built up, to anydesired depth, by external'blocks in the 'form of rings or frames c, and by internal frames or slabs b, all appropriately rein# forced. There may be several sets of nested or overlapping blocks b, dependent on the desired degree of strength, and the joints of these blocks are staggered relative to each.

other and to` the joints of the blocksV c so that no access to the interior of the safe is possible. The outer margins of thev slab a are reduced so, as to form, a.shoulder for holding the other blocks in position. AThe structure is terminatedA by a front frame d which `overlaps the blocks c and bi and which is recessed to receive a metal frame g and with it the door h of the safe. The frame g is connected either to a completebox f which ills up the interior of the safe, ormerely to straps which,l like the box, can be secured by means of nuts and by means of aclamping plate c to the bolts z'. The nuts can be tightened up ,forforcing the frame g to the block or frame d and the latter to the blocks b and c. Thus a firm structure is obtained which cannot be taken to pieces without acsired depth of the safe. Thus, apart from the ease with which the safe can be erected and removed, a considerable reduction in the cost of manufacture will be achieved. The fastening elements, lbeing enclosed within the safe, will be protected from fireas well as from breaking attacks. The rings vor frames c may bereplaced by plates adapt.- ed to interlock so as to be inseparable un til the internal fastening is removed.

Several safes or compartments may be lcombined into one structure, as shown in Figs. 3 to 11. The back sla'b a is in each case modified to accommodate the different cross-Walls formed by the blocks '6. The

blocks c embrace the entire structure, and

each safe or compartment isfitted with in dependent fastening elements, so that all the doors must be opened before the parts can be separated.

In the structure according to Figs. 3 to 6 two safes are arranged in this manner one above the other. Fi s. 7 and 8 show them arranged side by side, and Figs. 9 to 12 show how four safes may be combined in the manner just described. The safes may be arranged with the plates a and the doors in a horizontal instead of a vertical position, and they may be built into walls if desired.

The safe may be concealed by means of an ordinary piece of furniture made so as to fit over it.

A group of independent safes may be arranged in juxtaposition, as shown in Fig. 13, and interconnected by means of screwbolts or other elements passing from the interior of one safe to that of the next. In this arrangement new safes may be added to the group in proportion as required.

I claim 1. A safe composed of detachable blocks of masonry and having a rear wall in the form of a slab, a seriesof nested frames abutting against a recessed part of the slab and forming the side and the end wall, a front frame overlappingthe nested frames, and means for clamping the parts together between the slab and the front frame, such clamping means being arranged inside the door frame to the slab so as to clamp the nested frames between the front frame and the slab, such clamping means being arranged inside the safe, substantially as and for the purpose set forth.

3. In a safe formed of detachable blocks' of reinforced concrete, a rear .wall in the form of a slab, a series of nested frames abutting against a recessed part of the slab and forming the side and the end walls, a front frame overlapping the nested frames, a metal box fitted within the nested frame, a door frame integral with the metal box and recessed into said front frame, and screw-bolts connecting said box with the slab so as to lock the fra-me in position by the'engagement of the door frame with the front frame, said screw-bolts being concealed within the box, substantially asand for the purpose set forth.

REINHOLD BRUR.
